(1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953.

(2) The junction-to-ambient thermal resistance under natural convection is obtained in a simulation on a JEDEC-standard, high-K board, as specified in JESD51-7, in an environment described in JESD51-2a.

(3) The junction-to-case (top) thermal resistance is obtained by simulating a cold plate test on the package top. No specific JEDEC-standard test exists, but a close description can be found in the ANSI SEMI standard G30-88.

(4) The junction-to-board thermal resistance is obtained by simulating in an environment with a ring cold plate fixture to control the PCB temperature, as described in JESD51-8.

(5) The junction-to-top characterization parameter, ψ_JT, estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining θ_JA, using a procedure described in JESD51-2a (sections 6 and 7).

(6) The junction-to-board characterization parameter, ψ_JB, estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining θ_JA, using a procedure described in JESD51-2a (sections 6 and 7).

(7) The junction-to-case (bottom) thermal resistance is obtained by simulating a cold plate test on the exposed (power) pad. No specific JEDEC standard test exists, but a close description can be found in the ANSI SEMI standard G30-88.

8.5 Electrical Characteristics

Limits in standard type are for T_J = 25°C only; limits in boldface type apply over the junction temperature (T_J) range of -40°C to +125°C unless otherwise stated. Minimum and maximum limits are ensured through test, design, or statistical correlation. Typical values represent the most likely parametric norm at T_J = 25°C, and are provided for reference purposes only. Unless otherwise stated the following conditions apply: VIN = 48 V. See ⁽¹⁾ and ⁽³⁾.

8.6 SMBus Communications Timing Requirements and Definitions

PARAMETER		MIN	MAX	UNIT
ƒ_SMB	SMBus operating frequency	10	400	kHz
t_BUF	Bus free time between stop and start condition	1.3		µs
t_HD:STA	Hold time after (repeated) start condition. After this period, the first clock is generated.	0.6		µs
t_SU:STA	Repeated start condition setup time	0.6		µs
t_SU:STO	Stop condition setup time	0.6		µs
t_HD:DAT	Data hold time	85		ns
t_SU:DAT	Data setup time	100		ns
t_TIMEOUT	Clock low time-out⁽¹⁾	25	35	ms
t_LOW	Clock low period	1.5		µs
t_HIGH	Clock high period⁽²⁾	0.6		µs
t_LOW:SEXT	Cumulative clock low extend time (slave device)⁽³⁾		25	ms
t_LOW:MEXT	Cumulative low extend time (master device)⁽⁴⁾		10	ms
t_F	Clock or data fall time⁽⁵⁾	20	300	ns
t_R	Clock or data rise time⁽⁵⁾	20	300	ns

(1) Devices participating in a transfer will timeout when any clock low exceeds the value of t_TIMEOUT,MIN of 25 ms. Devices that have detected a timeout condition must reset the communication no later than t_TIMEOUT,MAX of 35 ms. The maximum value must be adhered to by both a master and a slave as it incorporates the cumulative stretch limit for both a master (10 ms) and a slave (25 ms).

(2) t_{HIGH MAX} provides a simple method for devices to detect bus idle conditions.

(3) t_LOW:SEXT is the cumulative time a slave device is allowed to extend the clock cycles in one message from the initial start to the stop. If a slave exceeds this time, it is expected to release both its clock and data lines and reset itself.

(4) t_LOW:MEXT is the cumulative time a master device is allowed to extend its clock cycles within each byte of a message as defined from start-to-ack, ack-to-ack, or ack-to-stop.

(5) Rise and fall time is defined as follows: t_R = ( V_ILMAX – 0.15) to (V_IHMIN + 0.15); t_F = 0.9 VDD to (V_ILMAX – 0.15)
